Title: Improvements in or relating to burners for liquid fuel or a mixture of pulverised fuel and oil usually known as colloidal fuel
IPC: F23D17/00
Filed: 1919-12-19
Abstract: 160,897. Robinson, J. G., Thom, R. A., and Vectis Engineering Co., Ltd. Dec. 19, 1919. Spray burners.-In a burner of the injector type for a composite fuel such as pulverized coal and oil, a hot inducing-fluid, preferably superheated steam, is employed for effecting the injection of the fuel and reducing its viscosity. A secondary annular supply of the inducing fluid is introduced between the central jet and the diverging burner nozzle at a greater velocity than that of the fuel. The primary supply is delivered through a central pipe which has a conical or diverging jet outlet and extends into a tapering nozzle forming the end of an annular fuel chamber heated by the pipe. More than one jet may be included in the casting for one burner, and control valves are provided so that each jet .may be used independently, or one, a number, or all may be brought into use as desired. Modifications to provide means for adjusting the angular position of the burner about hollow trunnions through which the fluid is supplied and for giving it an intermittent angular motion are described. Figs. 4 and 5 are a sectional elevation and plan of a three-jet burner, and Fig. 7 is a side elevation of the fuel and steam supply systems. The fuel inlet for each jet is inclined at less than 90‹ to the rear of the burner, and leads to an annular chamber b into which the steam-pipe c with inlet g<8> extends, terminating in the conical nozzle e. The outlet f of the fuel-chamber extends into a chamber having a steam inlet g<7> and leading to the diverging spatular ignition nozzle k. The shape of the outlet of the chamber and nozzle f cause the secondary steam supply to pass into the nozzle k at a greater velocity than that of the jet issuing from the nozzle f. In the form shown, the inlet a leads to the central fuel chamber b<2> and branch pipes a<3>, a<4> from the inlet a<2> lead to the outer chambers b<1>, b<3>. The fuel passages are controlled by valves l, m in a casting C secured to the main fuel supply D. The primary and secondary steam supplies are controlled by the valves PP<1> and QQ<1>.

Title: Improved machine for cutting off slices for toasted bread
IPC: B26D1/25
Filed: 1932-11-14
Abstract: 391,712. Slicing-machines. GRANGETTE, L., 87, Rue de la Republique, St.Mande, Seine, and COUSIN, F., 11, Rue de Madrid, Paris, both in France. Nov. 14, 1932, No. 32164. Convention date, Dec. 10, 1931. [Class 28 (ii).] A number of loaves, advancing intermittently along parallel paths, are cut simultaneously by a band saw carried in a vertically reciprocating mounting, the cut slices falling over a shoot to means which conveys them to a toasting-oven. The paths for the loaves are defined by spaced parallel vertical plates 14 held by straps 15. The plates 14 are positioned above a conveyer 3 which passes through slots 9, 10 in, and lies during its operative travel upon, a table 8. The conveyer is provided with spikes for engaging the loaves and moving them positively. At the end of the paths between the plates 14, the loaves are steadied by leaf springs 17 bearing on the loaf tops, and similar springs bearing on the loaves at one side. The conveyer 3 is driven intermittently by a cam 22 oscillating a roller-ended lever 21 which is connected to the arm 19 of a friction ratchet by a link 20 which is adjustable for varying the slice thickness. The band saw 1 is trained around pulleys 26 on parallel shafts 43, having tensioning-means and mounted on a frame 2 which is vertically reciprocated in bearings by a cam 33. One of the shafts 43 is driven by a belt-pulley 29 slidably splined thereon. The cut slices slide over a partitioned shoot 31 either directly on to the conveyer 5 or on to toasting grids supplied to the conveyer 5 by a conveyer 38. The machine is driven by a motor 41, the speed of operation being controlled by a change speed device 4, e.g. of the double cone type.

Title: Cooking machines such as a doughnut frying machine
IPC: A47J37/12
Filed: 1964-08-07
Abstract: 1,039,138. Frying apparatus for doughnuts. BELSHAW BROS. Inc. Aug. 7, 1964 [Aug. 19, 1963], No. 32195/64. Heading A4D. [Also in Division B8] In a frying apparatus having a flight conveyer for moving doughnuts through heated fat is a tank and a turn-over device, the conveyer is supported in the tank by a pair of check members detachably carried on the walls of the tank. Shaft 87 drives flight conveyer 25 by means of chain and sprocket drive 54, 55 and the co-axial sprockets 45 of a lifting conveyer 27. This continuous drive is transmitted by crank 95 and connecting rod 96 to arm 98, so that dough cutter 41 is oscillated on a vertical rod 35, between two limit positions overlying, respectively, the two sides of plate 63. Shaft 87 operates a micro-switch twice per revolution, thus energizing a dough cutter drive motor in each limit position. The cutter produces a dough blank at each operation before switching itself off, and dough blanks from consecutive operations sink side-by-side on to plate 63. As the blanks begin to cook they become buoyant and rise in engagement with a cross flight 59 of conveyer 25. An upstanding flange 70 of a two-bladed turnover device is positioned in the path of flights 59 so that the movement of each flight in contact with this flange rotates the blades to lift the doughnuts pushed by the following flight. A weighted lever 73 bears on a pair of crank pins to impart a flip-over action to the blades, thus depositing the inverted doughnuts in front of the blade-operating flight. Conveyer 27 lifts the cooked doughnuts out on to discharge ramp 52. The apparatus can be readily dismantled by removing the dough cutter, uncoupling and lifting out the conveyers 26, 27 and lifting out the thermostatically controlled heater unit 22 which supports heating element 145. The tank may then be removed from a supporting frame on which drive mechanism 28 is mounted.

Title: Improvements in and relating to the electric propulsion of ships
IPC: B63H23/24
Filed: 1934-11-08
Abstract: 450,086. Transmitting mechanical power. AKT.-GES. BROWN, BOVERI, & CIE, Baden, Switzerland. Nov. 8, 1934, No. 32204. Convention date, Nov. 8, 1933. [Class 38 (iv)] [See also Group XXIXI In a ship propelling system in which one or more generators supply one or more propeller motors, the speed of revolution of a disconnected and unloaded generator is dependent upon the speed of a motor. In the system shown in Fig. 1, either or both of the generators cl, c2 each driven by a turbine d1, d2, supply current through switches A1, A2 to a synchronous motor a, the control being effected by hydraulic means. The steam supply to the turbines is regulated by valves g1 g2 operated by pistons i1 i2 which are closed by springs and opened by oil pressure supplied through pipes 21, 22 from pumps k1, k2. The pressure of oil is regulated by leakage valves o1, o2 adjusted jointly by oil pressure in a pipe I supplied from a pump t and having a leakage control valve f. A further control of the operating pressure in the pipes 21, 22 is effected by centrifugal governors h1, h2 driven by the turbines and a governor m driven by the motor a. Each governor adjusts vertically a piston u1 or u2 co-operating with an opening in the wall of a sleeve which is forced downwardly by a spring and raised by oil pressure in the pipes 31, 32 under the control of leakage valves r1, r2 regulated by pressure in the pipe II under the control of a speed governor m driven by the motor a. The valve f thus controls the speed of either or both generator, while the governors h1, h2 limit their maximum speed in dependence upon the speed of the motor a. A stop may cut out the control of the generators by the governors below a certain speed. The idle generator may be maintained at a speed which is either above or below that of the motor. In the modification shown in Fig. 2, a tachometer dynamo m driven by the motor a, opposes either or both of the tachometer dynamos h1, h2 driven by the generators cl, c2, thereby operating relays o1, o2 controlling the prime movers d1, d2.

A method of making a turbine or compressor blade having a blade portion 4, Fig. 7, with an integral root 8 and platform 9 and having longitudinal cooling passages 2, comprises making holes longitudinally in a billet, Figs. 2, 8 (not shown), and filling them with a removable filler having similar flow characteristics to the billet metal, partially extruding the billet through a die 15, Fig. 3, to produce a blank having an extruded portion 4 for forming the blade and an unextruded portion 5, in which parts 6 of the holes are inclined, for forming the root and platform, and machining the root and platform whereby the inclined parts of the holes are intersected by a machined surface or surfaces and open at 10 in one or both sides of the root. The billet may be of a creep-resisting nickel chromium or nickel-chromium-cobalt alloy and the filler of an iron-manganese-titanium alloy. Blind holes are drilled in the billet and after filling, the solid end thereof is hot-extruded through the die 15 which has inclined surfaces 17 determining the inclination of the parts 6. Opposite sides 20, Fig. 5 (not shown), of the root are then curved by machining or gap rolling and the blank portion is hot forged in closed dies to aerofoil section, Fig. 6 (not shown). The root and platform are then machined. The solid end of the blade portion may be cut off to expose the holes or a shroud may be formed by upsetting the solid end and drilling holes therein to meet the passages 2. In another embodiment, Figs. 8-10 (not shown), only one row of holes are drilled in the billet to form passages which open into one side only of the blade root. The filler is removed by acid leaching or otherwise.

Title: Textile and film ornamentation
Inventor: BENTHAM RUSSELL
IPC: D06Q1/00
Filed: 1952-12-22
Abstract: Coloured pattern effects are produced on textiles or films made wholly or to a substantial extent of nitrogen-containing synthetic polymeric fibre- or film-forming materials capable of being dyed with anionic dyes by applying a mechanical pressure action in selected areas followed by dyeing, treatment with a resist for the dyestuff also being effected before or after the application of the mechanical pressure action or together with the dyeing operation.  The treatment is applicable to textiles and films of polyamides, polymethanes, polyesteramides, polyacrylonitrile and copolymers of acrylonitrile with, e.g. vinyl chloride or acetate, and the textiles may be in the form of fabrics, slubbings, rovings and yarns, which may be predyed, preprinted, prebleached or pretreated with fluorescent brightening agents.  Both the treatment with the resist and the dyeing operation may be locally applied.  As applied to slubbings, the dyeing operation may be effected before or after they are spun into yarns and woven into fabrics.  Further effects may be obtained by applying a second dyestuff, preferably from the same bath as the first dyestuff, whose acceptance by the fibre is not prevented by the resist.  At least some of the steps of the process may be repeated. The mechanical pressure action may be applied by a press, stamp, brush or engraved moulded or friction calender, or by the means described in Specification 752,191, whereby the selected areas are also compressively shrunk. Preferably the mechanical pressure means is heated and the textile or film is treated therewith in the wet condition.  Suitable resists, many of which are specified, are gaseous or wet chlorinating agents; mono- or poly-isocyanates or -isothiocyanates; sulphurized phenols and naphthols, metal-containing sulphurized phenols and naphthols and sulphonated sulphurized phenols and naphthols and their substitution products, and condensation products thereof with aldehydes or with amino-aldehydic condensation products such as those described in Specifications 552,015, 640,421 and 681,618; and synthetic tanning agents such as those described in Specifications 375,160 416,191 and 493,997.  In some case mordants may be employed for assisting the application of the resist as well the dyestuff, thus in dyeing polyacrylonitrile, a cuprous ion mordant may be employed for this purpose.  Dyeing may be effected with level dyeing acid, acid milling, chrome, premetallized, direct, basic, solubilized vat and fluorescent dyestuffs and, when the resist is a isocyanate or isothiocyanate, with disperse dyestuffs.  Numerous examples are given.
